Hydraulic and Pneumatic Locking Cylinder High Force Holding PFA
Self-Locking and Braking Cylinders
Self-Locking Cylinders function with common standard cylinder two port activation, but provide locking and holding forces up to 10 times more than a standard cylinder of the same bore size. Braking cylinders are less aggressive for holding force, but employ an internal to rod brake that allows holding loads at any location in the stroke.
